Title: Sohc vs Boss / size
Post by: bn69stang on October 12, 2013, 11:12:39 AM
When comparing a sohc 427 to a boss 429 in terms space in an engine compartment how do they compare ? .  how do they measure up in width , length , hood clearance  with each other ? .  Would a sohc 427 fit in a 1969-1970 mustang with the boss shock tower modifications ?

I don't know exact measurements, but in the only direct replacement situation I was anywhere near, Dennis German pulled the Cammer out of his Maverick and replaced it with a Boss 429 without any further cutting in the engine compartment.

I suppose I'd say that you must have enough $ in hand to work on either design that a bit of cutting would not be a deal breaker.  ;)

Yes, a 427 SOHC will fit in a Boss 429 Mustang engine compartment.

Can you imagine doing it to an original Boss 429... twice! It's a beautiful car and George is a great guy.

I remember when the original "Pops Toy" was stolen.....lots of magazine coverage and a healthy reward for the time.....Cory

I remember the Hot Rod magazine that featured the installation of the SOHC into the Boss 429 Mustang.  Great photo, right on the cover.  The hate mail from the purists after that issue was unbelievable.  But I thought it was about the coolest magazine cover I'd ever seen.  Anybody got a copy that they can scan and post a picture of?

Well Jay, of course I have a copy in the archives lol. Next time I see you I'll try to remember to bring it with. Until then here's a photo so people know what to look for.

I think that is one of the all time greatest Hot Rod magazine covers, right up there with the dyno shot of the cammer on the January '65 issue.  Thanks for posting that, Kevin; I figured you probably had that one...

Speaking of HR mag covers, I seem to remember a shot of Connie Kalitta's SOHC TF dragster... it was either a chassis dyno or wind tunnel shot.  That photo would rank right up there!

Wow, thought all here had seen the HR mag inside two-page pic (1965?) of Kalitta's Bounty Hunter rail in Ford's engine dyno test cell. It's actually both a wind tunnel and dyno.

Here's another shot from HR of the same test session. This IIRC was the actual HR cover shot, not the bigger side shot shown above.

The previous red zoomie pic, which I saw in high school (yikes!) was, I still think,  the all time coolest HR pic!

Ive seen them before .... Think they tested and found
the hot exhaust passing over the tires helped with the
streamlining or downforce or both or something :-\

 A guy up here in western NY has a boss 429 car that he dropped a SOHC into, Looks really deceiving, He ran it for a while but its been in storage for a while. This guy has quite a collection of cars and parts, He has abround 25 427s and a ton of parts, I bought a block from him yrs ago and stay in touch with him.

Yeah, good old Wind Tunnel #2.  They must have had that camera remotely activated because if I remember right there were no windows on that side and they would not have let anyone standout in the wind over 35 or 40 mph.  That is a real driver inside the car - heard about that.  They used the same tunnel for aero testing the GT40 and some other racing cars using load cells underneath the tires.

BTW, naturally a 429 crank is longer than a FE crank, but the Boss 429 crank is shorter overall than a FE crank because of the shorter snout. 

Last time I was measuring things, I think the mod engine is wider than the Boss 429.

IIRC, the 4V Modular is indeed wider than a Boss 9 or a SOHC.  The 2V head is narrower, so it may not get out quite as far, even at the 5.4L deck height.

I think the 427 SOHC is the best engine swap ever for a Boss Nine car, Pops got it right! Should be a Hooker header swap kit for it!! Thanks for the links to the cool vintage pictures too! Can someone post the picture where a fuel car is running over a SOHC crank assembly? Courtney.

It's a early model 392 Hemi, not a Ford SOHC.

That is another one of my all time favorite magazine photos; got it hanging up on the wall in my garage.  Literally running over the crank LOL!
